Completely agree. I have a set of Stack Audio Auva EQ footers on order and can’t wait to try them out as well. I tried placing paper weights on my streamer, transport and DAC last night and I was surprised by the improvements. Can’t wait to fire up the system today to check if what I heard is still there.

Have you tried both Model 70 and 100? I’m also interested in these feet. The 100 cost about 50% more than the 70. I’m wondering which one should I take? I have a wooden floor. If the 100 has five compartments instead of 3 and is twice as large in terms of area as the 70, they should probably be able to deal with vibrations better. Better to choose something too big than too small, right? Not that if I choose the 70’ to save on price and give away performance as they only offer half the effect as the 100’. And it is precisely this loss of performance that causes disappointment. What do you think Donald? My speakers weigh around 80kg. Maybe a little more. The 70 would be a little flatter but the Gaia, for example, would be much higher than the 100 Auva.

I have not tried 70. But when I talked to Stack Audio, they recommended to use AUVA100 for my FR30 speakers.But 100 is more effective in vibration control than 70, and for larger speakers I will recommend these.

I also thought it would be better to bite the bullet and choose the 100 as they probably have more than twice the chamber volume. Is the position fixed? What changes did you have in the sound? My sound is quite balanced, the bass can easily tip towards a bit too much. Depending on the cable, fuse, etc. That’s why I ask. I’m hoping for more precision but not more weight in the sound.

Simply and most importantly, AUVA100 excels in improving clarity and definition on all frequencies of my speakers. But since bass is more problematic and an easily heard area in most rooms, you will hear more improvement in this area.
Of course, all footer and vibration control devices should do that, AUVA 100 just does better than anything I have tried. I also like their EQ under gears, but one needs to be careful on where/how to use it because it could dampen the vibration too much.

Are you saying where/how to use as in which component to use it on or where to place the EQ under the component you’re using it on. I have heard that it is best used towards the edge on the component not towards the inner area. Could you clarify please?
I use it on Grimm MU2, and the best place to put them is under the feet of MU2, not under the body in my system. When placed them under the body (I use four), the SQ became a bit lifeless, and it was because the EQ dampened the gear too much, I believe.
However, I have not tried them under a different gear, but the previous Orea Indigo was not as sensitive as EQ in terms of placement.

I ended up replacing one of the three EQs with a Vibrapod cone, point facing up, and a Vibrapod combination. The sound immediately livened up and the bass became deeper and tighter.
That’s interesting to know. I have quite a few different footers in the storage and I have not tried others on MU2 yet. Now it’s time to experiment with them before my new gear shows up

Currently have :
RevoPod footers/Symposium Ultra Platforms under my MBL101E speakers and Taiko Extreme music server.
Critical Mass Center Stage footers under my EMM Labs DV2, Ansuz PowerBox, and Ediscreation Silent Switch.
Marigo Audio Labs Orpheus footers under my Rowland 925 amps and Firebird LPS.
I’m perfectly satisfied with this combination of footers.
System has never sounded better!

I don’t understand how devices used to rid components of unwanted vibrations could over dampen a unit, causing the “lifeless” sound from the MU2. Aren’t all footers imperfect devices, and the ones that reduce the most vibrations, the winner?
I’m not doubting your experience, but I thought footers were a set-and-forget item with the best design (AUVA?) the winner. The thought that a best result was achieved by placing the AUVA’s underneath an inferior stock foot baffles me.

A custom designed look. Nice choices.
Enjoy.

I may be one of the few that have tried more footers here on various gears than most, and the vibration-control devices all do what they claimed but some were more successful than others. Some footers have weighed limit for a good reason, and I found them played a rule in affecting SQ. AUVA EQ particularly affects the SQ more so than others. I first used their “2” which was designed for heavier equipment, and I did not like the sound at all. Josh sent me a set of inserts for lighter equipment, and the SQ has turned better.
Still, I like them better under the feet of MU2 than placing under the body because the sound is more vivid. More lifelike is how I would describe it. I will try them under different gear, and will use different footers in hand on MU2 to see what kind of result I will get.

@dchang05 comments remind me of those by Kevin Deal regarding microphony in tubes and the results of possibly over-damping.
" Can a tube be too low in microphony? Sometimes a little bit of microphony can be a good thing! In my opinion, tubes that have a smidge of microphony can lead to a sense of “air” or depth in soundstage. Using tube dampers can decrease, or even eliminate microphonics, but it can also remove that air and depth. Some folks don’t mind that, others do. If you have tube dampers, try using your tubes with them, then listen to the same tracks without, and make a judgement call… there’s no right or wrong answer here."

I don’t know if electro-mechanical induced vibrations are relatable to strictly mechanical ones. But I am not a scientist. Proof of the pudding is in the listening I guess. So may variables, so little time.

The comparison may not hold and it’s apples and oranges – I don’t know either. Just thought it was interesting.

Seriously, why could not these cheap moongel pads act as a better footer for many a device than many seriously expensive alternatives.
And aren’t they basically high-tech material in a way, moongel is a material engineered for a purpose.

And seriously, if we forget dampers and coupling in general, there are floating (suspended) solutions available. As in hanging from the roof or more practically as has been done, to hang the back of the speaker with steel wire suspenders at the rear and having a bearing at the front, this allows most of what hanging from the roof would.
Intetesting video measuring how differnt footers compare.
Since one the more affordable footers preformed best overall, I think I’ll give them a try on my speakers.

This is interesting. Looks like Tough cone excels in mid and high, and Stack footers win in bass area. I wonder which will be preferrable in a real world situation. Looking forward to hearing your review.
